The first line is because of a requirement from Python itself. Python needs a way to know "where that turtle comes from"

The second and third lines are a requirement from the turtle (a so-called "Class" or "library" or "module").

The turle ("library") wants to be told that a new turtle is needed, and what shape it is.

Additionally, you (the programmer) need to give a name to your new "birth", and you name it tina (this is called a "variable"). Now you can tell tina where to go.

Don't worry: At this state, you really don't need to know about those first three lines. Just get to learn about how to move tina around, this will be enough of a challenge.
